OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 404,297, dated May 28,1889.

Application filed September 3, 1888. Serial No. 284,490. (No model.)

To all whom it may concern:

Be it known that I, MARTIN D. MILLER, a citizen of the United States,residing at Leavenworth, county of Leavenworth, State of Karlsas, haveinvented a new and useful Oil- Burner for Stoves, Grates, &o., of whichthe following is a specification.

My invention relates to improvements in coil-oil burners, where coal-oilis burned as a fuel in stoves, grates, or furnaces; and the object of myimprovement is, first, to more elt'ectually commingle with the burningoil the air necessary to its complete combustion; second, to partiallyvaporize the oil and thereby increase its combustibility, and, third, topass the oil onto the burning hearth in afilm from between sheets ofmetal so close together that it is impossible for the air to enter andcommingle to form an explosive gas. I attain these objects by mechanismillustrated in the accompanying drawings, in which Figure 1 is aperspective vertical view of my invention. Fig. 2 is a View from thebottom, with a partial sectional view, showing the packing used toconfine the oil in place. Fig. 3 is a vertical sectional view taken onthe line 00 x of Fig. 2. Fig. 4 is the same view with flue attached.Fig. 5 is a longitudinal view of pipe used to convey oil from thereservoir to the burner. Fig. 6 is a vertical perspective and partialsectional view showing my burner attached to stove with reservoir andconnections.

Similar letters refer to similar parts throughout the several views.

A is a piece of gas-pipe of any preferred length and diameter, one endof which is provided with a coupling, a, and the other being capped, b,in the usual way. Along one side of the pipe are arranged holes 02 o o,through which the oil in the pipe escapes and passes through the spacebetween the plates 13 and B, which space is formed by bending plate Baround pipe A and back upon itself part of its length, as shown in Figs.3 and 4c. The balance of plate B not covered by B forms the hearth uponwhich the oil burns.

D is a metal plate forming a casing so shaped and bent as to form thefront and sides of a flue for directing the draft, and also has aneXtensionflV, passing downward from apex of burners to pipe A, havingprojecting ends D, which are to be bent under the plates B and Btofirmly hold such plates together, (see Fig. 2,) and also for thepurpose of holdin g D and W in position.

In Fig. 2 will be seen a partial sectional vi ew of the asbestus orother packing, d,which is to surround pipe A and fill the space betweenplates Band B, and serves the obvious purpose of preventing the oil fromtoo freely leaving pipe A.

C is a plate forming the back of the flue, and is held in position bythe bent projections on plate D, Fig. 4.

s 8 (see Figs. 2 and 4) are slots in plate B, having upward-projectinglips. Such holes or slots and the lips to same are arranged on an angleto the sides of B of about forty-five degrees, the lips being soarranged as to prevent the oil from flowing through the holes or slots.The slots serve the purpose of admitting air to commingle with theburning oil, and thereby effect complete combustion. Coupling a and capI) also serve the purpose of holding disk of asbestus packing againstthe edge of plate B, where it passes around pipe A. (See Fig. 2.)

Slots 1' 'i in plate D are to admit cold air to the products ofcombustion in the flue.

The oil coming from the reservoir through a pipe joined to coupling aenters pipeA and passes through the small holes 1) o 2) into the spacefilled with packing between plates B and B, and percolating through themeshes of such packing rises by its own force to the apeX,of the bend inplates B and B; thence downward between such plates to the hearth orplace of combustion on the end of plate 13 not overlapped by plate B.The space between plates B and B is shown at Z Z, Fig. 4.

The hearth, being an incline plane, enables the oil to cover and flowdown its surface while ignited, and the air entering slots 8 s and fromunder the lower end of plate B facilitates and completes combustion.

The heat communicated by platesB and B expands and partially vaporizesthe oil, in which condition it produces greater heat and is morecompletely consumed.
